摘要： A system and a method generates at least one signature associated with document. In one embodiment, a document comprised of text is received and parsed to generate a token set. The token set includes a plurality of tokens. Each token corresponds to the text in the document that is separated by a predefined character characteristic. A score is calculated for each token in the token set based on a frequency and distribution of the text in the document. Each token is then ranked based on the calculated score. A subset of the ranked tokes is selected and a signature is generated for each occurrence of the selected tokens. The selected list of signatures is then output.

摘要： A system generates an output of documents having with a particular relevance range. The system receives an initial document comprising text, a list of documents for matching, each document comprising text, and a minimum substring match length. The system normalizes the text of the documents of the list of documents. The system searches common sub-strings between the text of the initial document and the text of each document of the list of documents. The system calculates a match percentage based on the search common sub-strings and outputs documents having a match percentage corresponding to a predetermined value. Also disclosed is a process for generating an output of documents within a particular relevance range.
摘要翻译：系统产生具有特定相关性范围的文档的输出。系统接收包括文本的初始文档，用于匹配的文档的列表，每个文档包括文本和最小子串匹配长度。系统将文档列表的文档的文本归一化。系统在初始文档的文本和文档列表中的每个文档的文本之间搜索公共子字符串。系统基于搜索公共子串计算匹配百分比，并输出具有与预定值对应的匹配百分比的文档。还公开了用于在特定相关范围内生成文档的输出的过程。

摘要： An automated method of matching an input document to a set of documents from a document repository. A signature database is stored, the signature database including a document identifier and signatures generated by a first signature generator for each of the set of documents. The input document is received and signatures are generated for the input document using a second signature generator, and the signature database is searched using the signatures generated for the input document. The first and second signature generators are configured such that different numbers of signatures are generated for a same document. Other embodiments, aspects and features are also disclosed.

摘要： A system and method provides a graphical user interface (GUI) for users to monitor and manage sensitive information within an enterprise network. The GUI can provide users with information, such as the presence of input/output devices (I/O device), the location of documents containing sensitive information (sensitive documents), and the status of local security policy. The GUI can also provide users with real-time information, such as the occurrence of local security policy violations, the life-cycle of sensitive documents, and the sensitive information dynamic flow within the enterprise network.

摘要： A system (and a method) evaluates raw data from an application prior to modification of the raw data. The system inserts injection code into an application. The injection code is configured to hook an application. The application is configured to allow modification of the raw data. Modification includes encryption and/or compression. The system analyzes the raw data in a context of a predefined policy in response to the executing application reaching the injected code during execution. The system instructs the application to cease operating on the raw data in response to the predefined policy prohibiting further processing of the raw data or instructs the application to bypass the injection code in response to the predefined policy no prohibiting processing of the raw data.
摘要翻译：系统（和方法）在修改原始数据之前对应用程序的原始数据进行评估。系统将注入代码插入到应用程序中。注入代码配置为挂接应用程序。应用程序被配置为允许修改原始数据。修改包括加密和/或压缩。该系统在执行期间响应于执行的应用程序到达注入的代码，在预定义策略的上下文中分析原始数据。系统指示应用程序响应于禁止进一步处理原始数据的预定义策略停止对原始数据的操作，或者指示应用程序响应于预定义的策略而绕过注入代码，禁止对原始数据进行处理。
